My guess is, from your hashrates, that you aren't running cgminer with the --scrypt flag, which you need to. BBQCoin, like Litecoin, is based on the scrypt algorithm. Essentially your blocks are being rejected because your miner is doing the wrong kind of work.

Change the shaders to the amount of shaders your GPU has. And you can mess with the intensity as well but I found 12 works best if you want to use your computer while mining.

Save it as a .bat, not a .txt file.

Then just double click that .bat file to start mining. With BBQ you will still probably get a few rejects, I know that's what happens with me. I think it's because of the low hash rate and low difficulty.
